Olympus uses crop factor of x2 just like Nikon uses x1.5 and Canon x1.6. And what is wrong with "Mask Tapping" OR in other words "CROPPING" the edges of an image. Have you ever cropped an image?, I have all the time, we all do. The images are more square, I actually prefer them that way. But that has no effect on image quality.Originally Posted by OldClicker
